To determine the diagnostic accuracy of lung ultrasound and chest X-ray in diagnosing Acute Pulmonary Edema (APE) in patients presenting with acute dyspnea in emergency department. This study was conducted at the emergency department of Shifa International Hospital, Islamabad from 31st July 2018 to 31st January 2019.
